ABSTRACT In this paper, a new anisotropic meta-surface-based circularly polarized antenna is presented. The polarization of the radiating patch changes from linear to circular using the proposed meta-surface design. The reference antenna is designed on the FR-4 dielectric substrate of thickness of 1.6 mm (and 4.8 mm) to analyze the effects of meta-surface. The proposed meta-surface antenna exhibits impedance bandwidth (S11<–10 dB) of 1.34 GHz (3.24–4.58 GHz), 3-dB axial ratio bandwidth of 1.004 GHz (3.59–4.594 GHz), and a peak gain of 7.83 dBi.

基于各向异性超表面的宽带高增益圆极化贴片天线

摘要 在本文中，提出了一种新的基于各向异性超表面的圆极化天线。使用建议的超表面设计，辐射贴片的极化从线性变为圆形。参考天线设计在厚度为 1.6 mm（和 4.8 mm）的 FR-4 介电基板上，以分析超表面的影响。所提出的超表面天线具有 1.34 GHz (3.24–4.58 GHz) 的阻抗带宽 (S11<–10 dB)、1.004 GHz (3.59–4.594 GHz) 的 3 dB 轴比带宽和 7.83 dBi 的峰值增益。
